BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0003] (b) Description of the Prior Art

[0004] The conventional wireless data process and communication peripherals, e.g. mouse, keyboard, scanner, microphone, speaker, wireless RC, wireless Internet connection device, wireless phone, wireless detection device or wireless alarm device, operate essentially by RF electromagnetic wave or ultrasonic wave wireless communication for achieving more convenient communication. Within, the recent blue tooth technology has become an index of the wireless communication. However, the stored power of the portable source of any of those wireless communication devices is limited; and both of their drive and transmission circuits operate so far at a fixed and single working voltage level which then varies depending on the strength of the signal. Under operating conditions feature variable distance between the transmission and the receiving devices and drastic fluctuating communication environment, and a fixed drive voltage or a fixed power amplification factor being used to emit signals, the power generated in case of shorter range of communication usually is larger than as needed, resulting in waste of electric power and shorter power supply in subsequent communication.

SUMMARY OF THE INVENTION

[0005] The primary purpose of the present invention is to provide a wireless information device with its transmission power level adjustable. Depending on the communication signal strength required by the communication range and environment, the drive voltage or power amplification factor associate circuit of the transmission device is adjusted to select the drive voltage required by the operation of or the power amplification factor for transmission control of the transmission device, thus to avoid waste of electric power due to excessive strength of communication signal.
